Abstract

Due to its high tolerance to salinity and temperature, as well as its strong adaptability, Metapenaeus ensis holds an important position in the Chinese aquaculture industry. However, studies on the evaluation of its germplasm resources remain insufficient. This research conducted an in-depth comparative evaluation of M. ensis from three representative farming regions in China: Sanya, Zhuhai, and Raoping. The nutritional analysis of muscle tissue showed no statistically significant differences in crude ash, moisture, and crude protein content among the populations (p > 0.05). However, significant differences were observed in crude fat and total sugar content (p < 0.05). The MeSY and MeRP populations had higher crude fat content than the MeZH population (p < 0.05), while the MeZH population exhibited the highest total sugar content. In terms of amino acid composition, the MeSY population had relatively higher total essential amino acid content and proportion, as well as higher total amino acid content, both of which were statistically significant (p < 0.05). A fatty acid composition analysis further highlighted the advantages of the MeRP population in several key fatty acids (p < 0.05). Physiological and biochemical analyses showed no significant differences among the three populations in total antioxidant capacity, superoxide dismutase activity, or catalase activity (p > 0.05). A genetic diversity analysis indicated that M. ensis has relatively low diversity, with the MeSY population showing higher SNP density and nucleotide diversity. A genetic differentiation analysis revealed significant genetic differentiation between the MeSY and MeZH populations, while differentiation between the MeZH and MeRP populations was relatively smaller. This comprehensive assessment of nutritional components, amino acids, fatty acids, antioxidant capacity, and genetic diversity highlights the advantages of germplasm resources from different regions. These findings provide valuable insights for future research on the genetic characteristics and breeding potential of M. ensis.

全面评估来自三个不同种群的水蚤的营养价值、抗氧化潜力和遗传多样性。
由于其耐盐碱、耐高温、适应性强等特点,中华绒螯鲈在中国水产养殖业中占有重要地位。然而,对其种质资源的评价研究仍然不足。本研究对中国三个具有代表性的养殖区域的剑鱼种质资源进行了深入的比较评价:本研究对三亚、珠海和饶平三个具有代表性的养殖区的 M. ensis 进行了深入的比较评价。肌肉组织的营养分析表明,不同种群之间的粗灰分、水分和粗蛋白含量差异无统计学意义(P > 0.05)。但是,粗脂肪和总糖含量有明显差异(p < 0.05)。MeSY 和 MeRP 群体的粗脂肪含量高于 MeZH 群体(p < 0.05),而 MeZH 群体的总糖含量最高。在氨基酸组成方面,MeSY群体的必需氨基酸总含量和比例相对较高,氨基酸总含量也较高,两者均有统计学意义(p < 0.05)。脂肪酸组成分析进一步凸显了 MeRP 群体在几种关键脂肪酸方面的优势(p < 0.05)。生理生化分析表明,三个种群在总抗氧化能力、超氧化物歧化酶活性或过氧化氢酶活性方面没有显著差异(p > 0.05)。遗传多样性分析表明,M. ensis 的多样性相对较低,MeSY 群体的 SNP 密度和核苷酸多样性较高。遗传分化分析表明,MeSY 和 MeZH 群体之间存在明显的遗传分化,而 MeZH 和 MeRP 群体之间的分化相对较小。这项对营养成分、氨基酸、脂肪酸、抗氧化能力和遗传多样性的全面评估,凸显了不同地区种质资源的优势。这些发现为今后研究 M. ensis 的遗传特征和育种潜力提供了宝贵的启示。

期刊介绍: Biology (ISSN 2079-7737) is an international, peer-reviewed, quick-refereeing open access journal of Biological Science published by MDPI online. It publishes reviews, research papers and communications in all areas of biology and at the interface of related disciplines. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
